Answer:troposphere
Explanation:The troposphere is the layer that holds 80 percent of the total gas in the atmosphere.
The chemical at the heart of the air bag reaction is called sodium azide, or NaN3. CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags.
We can confirm that in a roller coaster, kinetic and potential energy in the car decreases at each successive hill because of the force of gravity which converts potential energy into kinetic energy.
<h3>What are potential and kinetic energy?</h3>
- Potential energy is referred to as <em><u>positional energy</u></em>.
- This means that the object in question gains energy based on its position relative to others.
- Kinetic energy is the energy of movement.
- Gravity causes the roller coaster to fall, losing potential energy.
- This causes it to gain all of the potential energy as kinetic energy.
- Once at the bottom, the coaster no longer moves and thus loses the kinetic energy as well.
Therefore, we can confirm that gravity is the force that causes the shift from potential energy to kinetic energy and thus causes them both to decrease after each successful hill in the roller coaster.

Answer:
we need to look at what actually happens to reactant molecules during a chemical. in order for the reaction to take place , some or all of the chemical bonds in the reactants must be broken so that the new bonds, those of the products , can form.
